Is there any problem with regard to the efficiency of the Polio vaccine in India?
The polio vaccine has gone through a rigorous process of testing by the WHO and the Government of India. There is no problem with the vaccine. However, sometimes, a drop in the efficacy, or effectiveness, of the vaccine may occur if it has not been maintained at the recommended temperature, as is the national protocol. The strict discipline and rigorous monitoring system built into the cold chain ensures that this does not happen.
